Bluetooth: Add AVRCP 1.3 as a developer option for AVRCP version (1/2)

This is requied for the 2012 Mazda 3 carkit as the carkit refuses to send
AVRCP commands other than passthrough commands when the version is anything
else. AVRCP 1.3 is compatible with most carkits on the market and can be
used to get most carkits working at the cost of losing many features.

Bug: 37943083
Test: Set AVRCP 1.3 in developer options and see that SDP and the AVRCP
      capabilites have updated to reflect this.
